Unity opens the explorer from the inspector interface, selects and records the file path

stay AvProVideo There are functions in the plug-in , Click the button in the video component to open the Explorer window , Find the target video resource and record the resource path .
After checking, it's not difficult to realize , There are two main points
One is unity The built-in method for opening the Explorer

EditorUtility.OpenFilePanel();

The second is to customize the operation of the editor

Implementation process
Script 1： define window 、 Open Explorer

using UnityEngine;
using UnityEditor;

public class Example : EditorWindow
{
    
    static GameObject _objectBuilderScript;
    //[MenuItem("SKFramework/Example")]
    public static void Open(GameObject objectBuilderScript)
    {
    
        GetWindow<Example>().Show();
        _objectBuilderScript = objectBuilderScript;
    }

    
    private string path;

    private void OnGUI()
    {
    
        // Horizontal layout 
        GUILayout.BeginHorizontal();
        {
    
            GUILayout.Label(" route ", GUILayout.Width(50f));
            path = GUILayout.TextField(path);
            if (GUILayout.Button(" Browse ", GUILayout.Width(50f)))
            {
    
            	// You don't need the pop-up window above 
                path = EditorUtility.OpenFilePanel(" It's a success  ୧*□*୨", Application.dataPath, "png");
                _objectBuilderScript.GetComponent<ObjectBuilderScript>().path = path;
            }
        }
        GUILayout.EndHorizontal();
    }
}

Script 2： Operation class

using UnityEditor;
using UnityEngine;
public class ObjectBuilderScript : MonoBehaviour
{
    
    public  string path;
    
    public void BuildObject()
    {
    
        Example.Open(gameObject);
    }   
}

Script 3： Override operation class
This script should be placed in Assets/Editor Under the folder

using UnityEngine;
using UnityEditor;
using System;
[CustomEditor(typeof(ObjectBuilderScript))]
public class ObjectBuilderEditor : Editor
{
    
    public override void OnInspectorGUI()
    {
    
        string path;
        string FilePath = Environment.CurrentDirectory;
        DrawDefaultInspector();
        ObjectBuilderScript myScript = (ObjectBuilderScript)target;
        if (GUILayout.Button(" Select picture resources "))
        {
                

            myScript.BuildObject();
        }
    }
}

You can see that we have defined a button

Popup

Open Explorer

After selecting the file, you can see that the path has been saved
